SN74F112N

Flip Flops Overview

The SN74F112N is a dual JK flip-flop integrated circuit belonging to the Texas Instruments 74F logic family. It features two independent JK-type elements with negative-edge triggering, complemented by active-low preset and clear inputs. The device utilizes a standard 16-pin PDIP package for through-hole mounting. Electrical specifications include a supply voltage range of 4.5 V to 5.5 V, a maximum clock frequency of 130 MHz, and a propagation delay of 6.5 ns at 5 V with 50 pF load. Output drive capabilities provide 20 mA low-level current and -1 mA high-level current, supporting operation within a commercial temperature range of 0°C to +70°C.

Flip Flops Feature Summary

• Dual JK flip-flops with negative-edge triggering

• High-speed 74F logic family performance
• Complementary outputs (Q and Q-bar)

Flip Flops Applications

• High-speed digital counting circuits
• Frequency division and pulse generation systems
• Shift register construction
• State machine implementation

Flip Flops Procurement Notes

Verify that the ordering suffix corresponds to the specific package variant required, as suffixes indicate physical form factor changes rather than functional differences. Confirm RoHS compliance status matches project requirements. Ensure the selected distributor source provides official datasheets for accurate pinout and electrical parameter validation before integration into final designs.

Flip Flops Selection Notes

Select this component when high switching speed is critical compared to standard TTL or LS families. The 74F series offers superior propagation delays suitable for demanding timing applications. Consider power consumption implications due to higher static currents inherent to the F family architecture. Evaluate thermal management needs given the bipolar transistor structure used in this logic family.

Flip Flops Part Context

This part belongs to the extensive Texas Instruments 74-series logic portfolio, specifically the fast F sub-family designed for high-performance digital applications. It serves as a fundamental sequential logic building block alongside other 74F devices like buffers, gates, and other flip-flops. The SN74F112N represents a legacy but widely recognized solution for discrete JK flip-flop implementations in industrial and consumer electronics.

Flip Flops Replacement Considerations

Direct substitutes include the SN74F112NSR surface-mount variant and cross-brand equivalents such as the MC74F112AN from ON Semiconductor. Verify pin compatibility and electrical characteristics match before substitution.
